Calibration Information:
Default Factory Calibration: The instrument has a default calibration with a capacity of 10,000 kg, load cell sensitivity of 2.000mV/V, and 1 division.
Theoretical Calibration: Use parameters EYPE, nChan, chan, du.dec, CAPAC, CEL.CAP, CEL.SEN, DEAD.Ld to perform a theoretical calibration.
Calibration Using Known Weight: Use parameters EYPE, nChan, chan, du.dec, CEL.CAP, 2Ero, SPAn to perform a standard calibration with a known weight. For parameters 2Ero & SPAn, press and wait for ERNOT, STORE?. Then press [enter key] to accept. For parameter SPAn, apply test weight before pressing [enter key].
Setpoint Programming
In the weigh mode, press and hold [enter key] to access output's setpoint programming.
| Parameter | Description |
|---|---|
| outPut | Select channel to be configured. |
| norni | Set the output normal state. |
| FunC | Setpoint on the gross weight. |
| Gro5 | Disabled. |
| net | Setpoint on the net weight. |
